-Samsung micro-USB 11-pin connector
-==================================
-
-Samsung micro-USB 11-pin connector is an extension of micro-USB connector.
-It is present in multiple Samsung mobile devices.
-It has additional pins to route MHL traffic simultanously with USB.
-
-The bindings are superset of usb-connector bindings for micro-USB connector[1].
-
-Required properties:
-- compatible: must be: "samsung,usb-connector-11pin", "usb-b-connector",
-- type: must be "micro".
-
-Required nodes:
-- any data bus to the connector should be modeled using the OF graph bindings
-  specified in bindings/graph.txt, unless the bus is between parent node and
-  the connector. Since single connector can have multpile data buses every bus
-  has assigned OF graph port number as follows:
-    0: High Speed (HS),
-    3: Mobile High-Definition Link (MHL), specific to 11-pin Samsung micro-USB.
-
-[1]: bindings/connector/usb-connector.yaml

-Example
--------
-
-Micro-USB connector with HS lines routed via controller (MUIC) and MHL lines
-connected to HDMI-MHL bridge (sii8620):
-
-muic-max77843@66 {

-       usb_con: connector {
-               compatible = "samsung,usb-connector-11pin", "usb-b-connector";
-               label = "micro-USB";
-               type = "micro";
-
-               ports {
-                       #address-cells = <1>;
-                       #size-cells = <0>;
-
-                       port@3 {
-                               reg = <3>;
-                               usb_con_mhl: endpoint {
-                                       remote-endpoint = <&sii8620_mhl>;
-                               };
-                       };
